One guy said that he's seen at least 1000 people online hate it, 500 in real life, has heard at least 20 conversations about it's badness, and saw a large group of at least 20 people holding up signs saying it's overrated.

I will admit, it's quite slow, but they animated it like that for a reason, I suppose.
Though, as the episodes progress, the animation picks up quite a lot. I have a few gifs as an example, but, like I said, it's anyone's opinion.

Most of them say it's just overrated, that "everyone watches it"
Others just don't care for it. It's hard to tell.
Like, in Anime Club, I always suggest that we watch at least one episode of Dragon Ball Z (it was the second to last week of school), and I somehow made everyone groan -_-
